In a completely out-from-left-field move. Anet has published a blog about the capitalizations of their race names and various grammar related issues related to their brainchild. Personally as an English major, this is a bold move to say that their writing goes through a strict editorial process before it's placed into the final game. It isn't a stretch to say that the overall package will be more consistent (like their skill naming conventions) and immersive literary work.
